Question
A boat covers 72 km downstream in 3 hours 36 minutes.
The ratio of the speed of the boat in still water to the speed of the stream is 3:1. Find the speed of the boat while going upstream.Solution
ATQ, Speed of boat in downstream = 72 ÷ 3.6 = 20 km/h
Let speed of boat in still water and speed of stream be 3x km/h and x km/h
Ratio of downstream to upstream = (3x + x)/(3x – x) = 4x/2x = 2:1
Therefore, speed upstream = (20 × 1)/2 = 10 km/h
